⚙️ Gunpla 4-1/2-Inch Diamond-Cup Grinding Wheel: High-Performance Tool for Concrete, Granite, Stone, Marble Review

This is a medium quality product which is priced 1/3 of the price of a similar branded product. It works with my Makita 4-1/2" angle grinder. It doesn't last long (mine ran 3 hours straight with cool down breaks) but I thought it was worth the money. For a larger work project it makes sense to have a backup I used a dust cover to catch most of the sanding dust - I advise all sanders to use it.

I needed to prepare an existing concrete surface for the application of QuiKrete Self-Leveling Compound. The best way to maintain a pristine surface for excellent adhesion is to "clean" the existing surface from the original pour down to uncontaminated concrete. This cup grinder did just that, quickly and easily using a 4 1/2" grinder. My six square foot job was fairly modest, but there was no noticeable wear on the diamond grinding surface. Aside from that subjective observation, my use was…

I did not receive the product shown in the photo. There are only 5 holes in the cup, not eight. Also, the base of the cup radius is too small to properly fit the flange nut. I'm going to cut out the washer and use a 5/8 nut. Okay, what did I expect for $15? Not much so I got what I expected. We'll see how it works in the driveway, so more details in a few days. Okay, in a few days and UPDATE. The thing really works! Cuts through concrete quickly and easily. It also left a decent finish, a few…

Works great on my 4 1/2" angle grinder with a 7/8" shank. Includes an extra washer , which looks like it will work with a 5/8" mandrel. It's just over 4 1/2" in diameter, so it barely turns without scratching the sheathing. I was a little worried about the fit as measurements are in metric units It cuts grout and concrete well but as you'd expect it doesn't do well on tile It cuts quite aggressively and can leave round gouges if you're not careful But this type of disc is designed for rough and

I bought this product because I thought it would take some time to remove and level some of the concrete that I set too high. How to level concrete and what should I do? It definitely removed the concrete and within minutes compared to the 30 or more minutes most videos state. The quality is rock solid. The diamond grit was barely removed from the tool itself after removing 1/4 inch from the stair step and then adding a slope to drain the water. Definitely recommend this to someone to buy for…

I usually tend to leave negative reviews or don't care. However, this wheel is unusual. I tried others and then I saw this. I had a large balcony with a cement floor that needed to be raised to replace the dry, rotting subfloor and create a slope for proper drainage. A lot of work. This thing ripped up concrete as fast as a wheel could turn. If I just wanted to remove the deck sealer I would grease the wheel and it would only remove the tip. I bought two but this bike looks like it will last…

Does not work with the grinder 4.5 inch porter cable applied. You cannot flip the jam nut like you would for a thin circle as it will not fit in the diamond cup that way. Update: Using a real turned 5/8 x 11 nut instead of a grinder jam nut it worked usable Then it proves to be worth the money Used it to sand a concrete slab in the kitchen where there are bumps Make your own dust cap out of cardboard with 2 holes one for the hands and one for the vacuum hose, taped shut I lined the top sighting

Works great when used with a regular Dewalt grinder. I don't write reviews, I read them but I'm about to do one for it, it works great. I had a stubborn flimsy set in my entryway of my house, I don't know what they did, looks like they used some sort of self leveling concrete and put the flimsy set on top of it while it was still wet. I've tried everything to make it smooth enough to put wood floors in, I saw these sanding wheels at Home Depot for over $50, I think I'd try this cheaper one, and
